Valid To This field displays the date that the certificate expires. The text

displays in red and includes an Expiring! or Expired! message if the

certificate is about to expire or has already expired.

Key Algorithm This field displays the type of algorithm that was used to generate

the certificate key pair (the Business Secure Router uses RSA

encryption) and the length of the key set in bits (1 024-bits, for

example).

Subject Alternative

Name

This (optional) field displays the certificate owner‘s IP address (IP),

domain name (DNS), or e-mail address (EMAIL).

Key Usage This field displays for what functions the certificate key can be used.

For example, DigitalSignature means that the key can be used to

sign certificates and KeyEncipherment means that the key can be

used to encrypt text.

Basic Constraint This field displays general information about the certificate. For

example, Subject Type=CA means that this is a certification authority

certificate and Path Length Constraint=1 means that there can only

be one certification authority in the certification path of the certificate.

MD5 Fingerprint This is the message digest of the certificate that the Business Secure

Router calculated using the MD5 algorithm. You cannot use this

value to verify that this is the remote host’s actual certificate because

the Business Secure Router has signed the certificate; thus causing

this value to be different from that of the remote host’s actual

certificate. See “Verifying a certificate of a trusted remote host” on

page 287 for how to verify a remote host’s certificate.

SHA1 Fingerprint This is the message digest of the certificate that the Business Secure

Router calculated using the SHA1 algorithm. You cannot use this

value to verify that this is the remote host’s actual certificate because

the Business Secure Router has signed the certificate; thus causing

this value to be different from that of the remote host’s actual

certificate. See “Verifying a certificate of a trusted remote host” on

page 287 for how to verify a remote host’s certificate.

Certificate in PEM

(Base-64)

Encoded Format

This read-only text box displays the certificate or certification request

in Privacy Enhanced Mail (PEM) format. PEM uses 64 ASCII

characters to convert the binary certificate into a printable form.

You can copy and paste the certificate into an e-mail to send to

friends or colleagues or you can copy and paste the certificate into a

text editor and save the file on a management computer for later

distribution (through floppy disk for example).

Export Click this button and then Save in the File Download screen. The

Save As screen displays. Browse to the location that you want to

use and click Save.
